Obama's Teary Thank-You to Staff

President Obama, thanking campaign staff at his Chicago headquarters, became as emotional as we've ever seen him, wiping tears from his eyes as he told the group, "When people ask me about how do you put up with this or that and the frustration of Washington, I just think about you."

He began by recalling how he "grew up" during his time as a community organizer in Chicago, saying the work "changed me much more than I changed the communities."

"I became a man during that process. And so when I come here and when I look at all of you, what comes to mind is not that you guys actually remind me of myself, it's the fact that you are so much better than I was, in so many ways," Obama said.

His voice cracked with emotion as he continued.

"I'm absolutely confident that all of you are going to do just amazing things in your lives," he said. "What Bobby Kennedy called the ripples of hope that come out when you throw a stone in a lake -- that's going to be all of you.
